Symmetry enforced entanglement in maximally mixed states
Amin Moharramipour, Leonardo A. Lessa, Chong Wang +2
Entanglement in quantum many-body systems is typically fragile to interactions with the environment. Generic unital quantum channels, for example, have the maximally mixed state wi…
Strong-to-Weak Spontaneous Symmetry Breaking in Mixed Quantum States
Leonardo A. Lessa, Ruochen Ma, Jian-Hao Zhang +3
Symmetry in mixed quantum states can manifest in two distinct forms: strong symmetry, where each individual pure state in the quantum ensemble is symmetric with the same charge, an…
Mixed-state quantum anomaly and multipartite entanglement
Leonardo A. Lessa, Meng Cheng, Chong Wang
Quantum entanglement measures of many-body states have been increasingly useful to characterize phases of matter. Here we explore a surprising connection between mixed state entang…
